Notes:
A new morphological mutant, Saccharomyces cerevisiae JD7, was isolated. This mutant had a mycelial-like form on a complex medium and a yeast-like form on a nutritionally simple medium or on a complex medium with 20% sorbitol. JD7 appeared to be a cell division cycle mutant blocked after nuclear migration and before nuclear division. No significant differences in RNA or protein contents were observed between JD7 and control strain A364A. JD7 cells settled much faster than control cells, and the viscosity vs cell concentration relationships were dependent upon the morphological conditions of the yeast. Yield stress of strain JD7 was barely observable, and the flow behavior index of the strain was similar to that of the control strain in its yeast-like form. The flow behavior index of the mycelial-like form was lower than that of the yeast-like state.
